To @ZZ i12/tom t may concern Be it known that We, WILLIAM li. l/VIL- HELM, drei-1N A.; Animar, and HARRY t Bieren, citizens the United States, re siding at Akron, in the county ot Summit and State of Ghia, have invented new and useful improvements in Separatore, of which the following is a specication.

This invention relates to improvements in separators or ccncentrators and has particular application to .a pneumatic separan tor.

ln carrying out the present invention, it is our purpose to provide a pneumatic separator wherein by means of the air passing through thelseparator the heavy-particles of the matter -to be separated may be sepa-- rated from the relatively light particles and the light particles carried away from the heavy particles.

, lt is also our purpose to provide a separator ot the class described wherein the material will he delivered to the separating table in a' number ott separate streams and pen mitted to ovv' from one table onto another While the'air is drawn through the separator, thereby enabling such air to remove the relativebT light particles from. the heavgr particles sothat the tailings may be separated from the concentrates, the dividing ot' the material into individual streams serving to augment the action ofthe air.

Another object of our invention is to provide a separator ot the classv described wherein the tables may be adjusted relativeif/ to one anothervso that the air space betnveen the samev may be varied and Whereinthe.componentv parts will' be so arranged and correlated that access may be yreadily had to the interior ol the separator to ia-1 cilitate the adjusting ofthe tables and to ena-bie the parts to be'clea-ned or replaced Whenever necessary.,

With the above and other objects in View, the invention consists in the constructign,

Fig. 5 is cross sectional view therethrough. Fig. 6 is a fragmentary top plan view of the separator.

Referring now to the drawings in detail, l designates a vertical casing substantially rectangular' in'cross section. Uprising from the bottom Awall of the casing 1 adjacent to,l

one end wall thereof and parallel with such 3 end wall vis a partition 2 of a Width equal to the similar dimension of the casing and having the upper end thereof terminating below the top Wall et the casing, While dei pending from the top Wall of the casing is a vertical partition 3 disposed behind the partition at a point approximately een ltrally of distance between the. partition 2 and the remaining end Wall ci the casing and the lower end of the partition 3 terminates above the bottom of the casing.'

'lihe end Walls ci the casing l and the parti# tions 2 and 3 cooperate to term a sinuous air passage and the bottom Wall of the casing 1 at the lower end of the iront leg ot the air passage is termed to provide a dependiirg hopper-shaped trough t having the side Walls Ythereof lformed with air inlet openings 5 and the lower Wall formed with a discharge opening 6, While formed., in the'-A top Wall ot' the casing at the upper end ofthe rear leg of the sinuous air passage is an opening 7 and connected With the opening 7 is one end ot a conduit 8 having the remaining end thereof leading into the casing olf a suction fan 9 whereby air may be drawn through'the sinuous passage in the easing. IThe bottom Wall oi the casing 1 at the juncture of the central leg of the sinuous air passage with the rear leg is formed to provide a depending' ll-shaped trough 10 and one Wall of the lv-shaped trough 10 is.

equipped with a hinged valve plate 11 normaily held in closedl position by means of a spring 12 and capable of movement to open position under the `Weight of the conf tents of the troughvi to release the 'contents from the trmi'gglal` Secured to the partition 2 at a point approximately centrally thereof and projecting across the front leg of the sinuous air passage is a downwardly inclined table 13 comprising a stationarysecton 1 4 and an adjustable section 15 secured to the under surface out the stationary section and capable ,of movement toward and away from .the front endfvvah of'the'casingto vary the dls- )tance between the lower edge of the table titl 'Secured to the upper end of the spout 26 is f'ahopper 31 and communication between the -.l1'opper 31 and the' spout is controlled by the and the front end wall ofthe casing. In the present instance, the stationary and movable sections ,14: and ll'of the table 13 are' formed with cooperatingl slot 17 and opening respectively through which is passed a se curing bolt 1S having one end equipped with a thumb nut 19, the bolt 18 and nut 19 'coacting to hold the sections of the table inv the desired adjusted position. This table 13, vof course, entends across the entire width ofthe front leg of the sinuous air passage.v Formed in the front end `wall of the casing adjacent to the table 13 is an opening 20 eX- tending across the front wall and detachably securedwithin the opening 20 and lnormally closing thelatter is a plate 21. Mounted upon the inner surface of the plate 21 is a vtable 22 comprising, in the present instance,

a hollow section triangular in cross section and having the bottom wall thereof lying parallel with the table 13 and the top wallinclined downwardly from the plate l21 toward the rear end of the'table 13 so that any material discharged upon the upper surface of the'table V22 will gravitate vonto the table 13. 1n the present instance, the

l,front wall of the hollow section forming the table 22 is fastened to the plate 21 by means gef-headed bolts 23 passed through vertical slots A2&1 respectively formed in the plate 21- .and 'equipped with thumb 'nuts lly I lmeans of the bolts 23 and the slots 24, the

table22 may be adjusted vertically' within the casing so-that the space between the discharge end of the table 22 and the receiving 1 end of the table 13 may be varied. `r1`heatable y22 is of a length equal to the table 13. Disposed within'the casing 1 above the table 22 Vand secured to the front end wall of the casing is a vertical inlet spout 26 having the side walls thereof converging downwardly toward eachother so that the lowerend of yplate 29 having openings 30 formed therein corresponding to the openings 27 and adapted to be'mov'ed into and out of registration with the openings 27, respectively.

valve plate29. The lowerend of the spout 26 terminates above the upper surface of the table 22 and connected with the lower end ofthe spout is adischarge nozzle 32 having the front and back walls thereof converging downwardly toward each other and the side walls diverging outwardly from 'each other from the upper end toward the lower end of the spout..y Secured `to the confronting faces of the front and back walls of the spout 32 are` division plates 33 coriesponding in position to the positions of the end walls of the nozzle 32 an'd spaced apart and adapted to divide the material passing through the nozzle into individual streams so that such material will be distributed over the table 22 evenly and uniformly. In the present instance, the opening 7 iin' the top wall of the casing 1 is controlled by means of a slidingplate 34 operable. to establish and cut olf communication between the conduit 8 and the casing 14 and to vary the size of the opening 7,

l In practice, the material to be treated is deposited in the hopper 31, the.valve plate 29'actuated to open position so that such material may pass through the spout 26, and the fan 9 set in operation. The material passing through thel spo'ut 26 4enters the nozzle 32 and is divided into streams by thc division plates 33 and distributed over the entire surface of the table 22 and passes down the table 22 and onto the table' 13. The air being drawn through the casing under the action of the fan 9 passes through the material dropping from the table 22 onto the table 13 and separates the light particles from the relatively heavy particles and permits the heavy particles to slide down the table 13 and into the hopper 4. Owing to the shape of the air passage, the light par ticles are carried downwardly through the central leg of such passage and as they reach the lower end ofsuch leg, drop into the V- shaped trough 10. Should any of the light particlesgravitate down the table 13 with the heavier particles, such light particles will be separated from the heavy particlesy when the material falls from the table 13.

"When a certain quantity of the light particles accumulate in the trough 10, such quantity or volume being determined by the strength of the'sp'ri'ng 12, the valve 11 opens under the weight of'thematerial and permits the latter to gravitate from thetrough, thereby automatically releasing the material from the trough so that choking of the separator will be eliminated. The corners of the sinuous air passage at the upper ends of the front and central legs are preferablyround edas at 35 so as to facilitate the drawing of the air through the sinuous passage.

While we have herein shown and described one preferred form of our invention by way of illustration, we wish it to be understood the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims without departing from the spirit of the invention.

We claim: 1.
